From d659fe8666c4bc38fcbdbe7b7a35101f2d7cc41b Mon Sep 17 00:00:00 2001 From: John Kehayias Date: Sun, 15 Feb 2026 23:35:20 -0500 Subject: gnu: glibc: Graft with fix for unsafe env variable [security-fixes]. Before this change, the environment variable GUIX_LOCPATH is not in the unsafe variable list, meaning that it is not unset in a privileged environment. This could lead to potential security issues. A CVE number is pending for this issue. A similar upstream glibc issue was CVE-2023-4911. * gnu/packages/base.scm (glibc)[replacement]: Add field to graft with ... (glibc/fixed): ... this new package. * gnu/packages/patches/glibc-guix-locpath.patch: New file. * gnu/local.mk (dist_patch_DATA): Register it.
